What is Fonoster?

Fonoster ships four releases in a day to make linking a Twilio number a single step.

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

What is Rocket.Chat?

Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

Fonoster vs Rocket.Chat: editorial side-by-side

F6.3

Fonoster ships four releases in a day to make linking a Twilio number a single step.

◆ Current state

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

◆ Where it's heading

After rebuilding its SIP and media edge and defaulting to HTTPS in the 0.31 to 0.33 run, Fonoster is now working on onboarding, using Twilio as the way to bring an existing number. The release rate stays very high and breaking changes still land in minor versions.

◆ Prediction

Expect the same number-linking flow for other carriers, or more Numbers page work; the entries only cover Twilio so far.

Rocket.Chat logo6.3

Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.

◆ Current state

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

◆ Where it's heading

Two threads run at once and point in different directions. The calling stack keeps maturing on its own — voice, then screen sharing, now a consistent in-room surface for both — which is Rocket.Chat absorbing functions its users would otherwise reach for a separate tool to get. Against that, the 9.0 licence requirement for LDAP and SAML sorts the install base: regulated and government deployments that will pay, and unlicensed self-hosted workspaces that were there for the absence of a per-seat bill. The rc train itself has settled into a familiar shape, one substantive rc.0 followed by bumps and fixes.

◆ Prediction

Expect 8.8 to go final once the message-list fixes settle, with the LDAP and SAML licence requirement, not any calling feature, as the story of 9.0. The open question is whether the Deno-to-Node runtime switch surfaces app compatibility reports before then.
